Description

  The present invention relates to a modified sash that can be attached to a new window frame without removing the existing window frame, and in particular, an interposition member is interposed between the existing window frame and the new window frame. In a renovated sash that attaches a new window frame, the space formed between the existing window frame and the new window frame is blocked by an inexpensive and simple structure by using an interposition member. At the same time, the present invention relates to a refurbishment sash and a rehabilitation method for a sash that can be easily renovated by correcting the problem with the member according to the present invention and the structure using the member, even if the housing has a defect such as distortion, flexure, or inclination. It is.

2. Description of the Related Art Conventionally, in a construction method for renovating a window frame of a building, a so-called cover method is known in which a new window frame can be easily attached without removing the existing window frame.
This method has various advantages such as no need to remove the existing window frame, no need to break the outer wall, etc., no need for scaffolding, less construction sound, short construction period, no dust and waste. Very useful as a way to refurbish the sash.
At present, many inventions relating to the cover construction method have been made, and the present invention particularly relates to a modified sash and a sash for attaching a new window frame via an interposition member between the existing window frame and the new window frame. This invention relates to a refurbishment method.

The refurbishment sash for attaching a new window frame via the interposition member and the method for refurbishing the sash form a space between the existing window frame and the new window frame via the interposition member, and this space is the window frame. It communicates indoors and outdoors over four laps.
Therefore, it is necessary to close the space, and a member for that purpose is required.

The following patent documents are disclosed as conventional techniques for closing the space.
According to the invention according to the following patent document, an external attachment is provided on the outer peripheral part of the outdoor side of the new window frame, and the space formed between the new window frame and the existing window frame is closed by this external attachment.
JP-A-9-13797

  However, when the sash needs to be refurbished, there are many cases where there are problems such as distortion, flexure, tilt, etc. in the frame and pillars around the window frame. Even if the new window frame is attached as it is, the space generated between the existing window frame is not constant on all four sides, and for example, the upper frame of the window frame is not horizontal. In general, such a problem usually occurs greatly.

Furthermore, such distortion, deflection, and inclination of the housing may occur not only in the vertical and horizontal directions, but also in the horizontal direction, and may occur three-dimensionally.
Moreover, all the defects of such a case are not uniform and are individually different.
For this reason, renovation of the sash is inefficient because it must be done individually for each case, and it requires a high degree of skill in the construction. There was a problem that it could not be corrected.

However, since the invention according to the above-mentioned patent document is a structure in which the external attachment is fixed to an anchor provided in the new window frame, when trying to attach to the existing window frame in a state where the external attachment is fixed in advance to the new window frame, The mounting position cannot be adjusted by moving the anchor provided in the new window frame with respect to the base material fixed to the existing window frame.
For this reason, as described above, when the housing has problems such as distortion, bending, and inclination, the invention according to the above-mentioned patent document may not be able to attach the new window frame to the existing window frame.

In addition to the inventions according to the above-mentioned patent documents, conventionally, a bent plate or a press-formed curved plate or an extruded profile has been used as a member for closing the space.
However, these members have been made to order according to individual window frames because of the problems caused by the above-mentioned problems of the casing, and thus the construction cost has become high.
Furthermore, the production of members such as curved plates and extruded profiles requires a thorough field survey and accurate measurement.
However, the greater the severity of the defect, the more measurement points are required or accurate measurement is required, but if the measurement points are insufficient or the measurement is inaccurate, the produced curved plate, extruded profile, etc. Of course, the components are wasted and must be remeasured and remanufactured.

However, field surveys and measurements require specialized knowledge and skilled experience, and the human burden is large, increasing the construction cost.
In addition, when a new window frame is attached by welding, a welding machine is required, which may cause a fire.
Refurbishment of sashes often involves construction while using the building, so it is important that the construction period is short and that it can be constructed easily, but it is also important that there is no risk of fire.

  Therefore, the present invention is an invention relating to a renovated sash that can be attached to a new window frame without removing the existing window frame, and has been made in view of the above-described problems, and in particular, between the existing window frame and the new window frame. In a renovated sash that attaches a new window frame via an intervening member, the space formed between the existing window frame and the new window frame is made inexpensive by using an intervening member. And a renovated sash that can be easily renovated by correcting the problem with the member according to the present invention and the structure using the member, even if the housing is closed with a simple structure, and there is a problem such as distortion, flexure, or inclination of the housing.

Hereinafter, a 1st Example is described with a construction procedure.
FIG. 1 is a longitudinal sectional view after the construction of the modified sash according to the first embodiment.
FIG. 2 is a cross-sectional view of the modified sash according to the first embodiment after construction.

The new window frame 1 is configured to be attached inside the existing window frame 2.
The existing window frame 2 is composed of an upper frame 2a, left and right vertical frames 2b, 2c, and a lower frame 2d made of steel or aluminum, and is left without being removed from the casing. It is.
The existing window frame 2 has a bolt 3 inserted into each frame 2a to 2d of the existing window frame, and is fixed to the housing.
The new window frame 1 is composed of an upper frame 1a, left and right vertical frames 1b, 1c, and a lower frame 1d made of steel or aluminum.
The new window frame 1 is attached by caulking the anchor 4 screwed to the bolt 3 at the approximate center of the frames 1a to 1d of the new window frame.
In this way, the new window frame 1 is attached to the existing window frame 2 without welding via the interposing members 3 and 4.

The new window frame 1 can be attached to the existing window frame 2 by welding.
